lcomes to rest,'cams 44 shift shafts 31^in wardly toward body-12 andbring rollers 38 into engagement with the projected end of the blankbody 30 and flanges the same outwardly as indicated in Fig. 6, the head32 being rotated by the pinions 45 as al-` l lready described.Immediately the Hanging 4 heads are' withdrawn and shaft 1l givenanother quarter turn 4thus advancing the 'Hrst blankto the point D. As`soon as the' parts' start.from point C theclamp 14 is engaged by aspring urged hook which away from its socket13 as shown at the loxverpart of Fig. 4. Socket 13 is just a triHe less than a semi-cylinder'sothat in practice the blank body is apt to'stick in the coperatingelamp14 and in order to insure the discharge' of the Hanged blank therefrom Imount in 'each of said clamps 14 an ejector finger 51 having an end 52,

which, when the parts reach the position D,

lies in the path of .movementx of a finger 53 Vcarried by shaft 22 sothat', as said sha-ft rotates -it will-'bring finger 53', intoengagement with the ejector and eject the flanged can body into the..discharge run-way 54.

In order to steady the partsduring the operation of the ej ecting intothe ejector I pro vide a hook 55 adapted .to engage roller 16.

In order to limit the step-by-step movement' of shaft 1,1 and insuretheA proper positioning of head 12 I mounta brake-.head
